Description : Replaces all elements satisfying equal to old_value with new_value in the range [first, last).
Example:
std::vector<int> origin {3, 5, 3, 1, 2, 3};
// replaces 3 by 0
std::replace(origin.begin(), //first
origin.end(), //last
3, //old_vale
0 //new_value
);
// origin is now {0, 5, 0, 1, 2, 0}
for (auto value : origin) {
std::cout << value << " ";
}
